    Abstract: Dithiocarbonate derivatives are disclosed, along with a process for preparing the same. The dithiocarbonate compounds can be utilized as initators, chain transfer agents and/or terminators in controlled free radical polymerizations. The dithiocarbonates can be used to produce polymers having narrow molecular weight distribution. Advantageously, the compounds of the present invention can also introduce functional groups into the resulting polymers. The dithiocarbonate compounds have low odor and are substantially colorless.

    Abstract: A method of preparing polymer, the method comprising polymerizing one or more ethylenically unsaturated monomers of formula (I) where U is selected from H, C1-C4 alkyl or halogen; V is halogen or of the form O-G where G is selected from —C(O)R1 and —R1, or V is of the form NGGa where G is as defined above and Ga is selected from H and R1, G and Ga form together with N a heterocyclic ring, or V is of the form CH2Gb where Gb is selected from H, R1, OH, OR1, NR12, PR12, P(O)R12, P(OR1)2, SR1, SOR1, and SO2R1; and where the or each R1 is independently selected from optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted arylalkyl, optionally substituted heteroarylalkyl, optionally substituted alkylaryl, optionally substituted alkylheteroaryl, and an optionally substituted polymer chain, under the control of a RAFT agent of formula (II) or (III), where Y is a Lewis base moiety and Y* is an n-valent Lewis base moiety; X is O or NR1, R1 is as defined above or forms together with Y or Y* and N a heterocyclic ring; m is an integer ≧1; n is an integer ≧2; and where R* is a m-valent radical leaving group that affords R*. which initiates free radical polymerization of the one or more ethylenically unsaturated monomers of formula (I), and R is a free radical leaving group that affords R. which initiates free radical polymerization of the one or more ethylenically unsaturated monomers of formula (I).
